strategic decisions that have changed the company dramatically in size and type of products offered. Clorox exited businesses that were not doing well (insecticides‚ bottled water‚ restaurant equipment) and built up its core brands with new products (bleach gel pen). Clorox used acquisition strategy to buy First Brands Corp. giving it a number of nationally known brands including the Glad line of plastic food and trash bags.

I used to bleach and dye my hair a different color every month when I was in high school. (my hair is hot pink and black in my senior picture) I have tried almost every semi-permanent metallic dye and that’s definitely what you see pictured above. The colors look like After Midnight Blue (dark blue)‚ Bad Boy Blue (light blue)‚ Hot Hot Pink (dark pink)‚ and Cotton Candy Pink (light pink)‚ all by M-P. I hope this helps.

The disinfectant that will prevent the growth of bacteria the most is bleach. Procedure: To begin the lab‚ turn the agar plate over and divide the plate into four quadrants and label the agar plate whether you used the E. coli or B. megaterium and number the quadrants 1 through 4.

Method says bleach is nasty stuff and doesn’t get your clothes clean; better yet we don’t need it to get our clothes clean. Method states that their technology in their product can get our clothes clean without bleach. This is a product we don’t need in our home. Method states that bleach and other surface cleaners contain all sorts of nasty chemicals that are toxic to breathe

Cleaning Seashells: 1. Burying - This one is pretty simple. Find an area in your yard where you don’t mind digging a hole and bury the shells about 18" down. The reason for the depth is so animals will not find them and dig them up. Also you or your neighbors won’t smell them. Let them remain buried until the insects‚ ants‚ larvae‚ worms and bacteria remove all the tissue and they will darn near polish the inside of the shell. But‚ this could take as long as a couple of months. The longer you
